   Scenario: Error handling
     When I attempt to call the "GetEventSourceMapping" API with:
-    | UUID | fake-uuid |
-    Then I expect the response error code to be "ValidationException"
+    | UUID |  deadbeef-e025-4d45-9da3-23813f5e7b65 |
+    Then I expect the response error code to be "ResourceNotFoundException"
     And I expect the response error message to include:
     """
     does not exist
